Ensure all regions are loaded into spatial index + misc validation fixes

* Currently only the first 1000 rows from a georegion dataset are loaded into the spatial index. Specifying an explicit limit of long.max so we don't cut off large georegion datasets.
* Allow through reprojected lons/lats that are basically valid
* New param to bypass feature validation
Also note it is in query-coordinator reference.conf, so I'd just remove it from reference.conf and the chef config.  Before merging this.
